ASME SA387 Grade 91 Class 1 Plates – Superior Creep Strength for Harsh Environments
Conquest Steel & Alloys is a well-known stockholder and exporter of ASME SA387 Grade 91 Class 1 Plates, renowned for its excellent performance at harsh temperature and pressure. These plates are fabricated from a super strength chromium-molybdenum-vanadium steel alloy that provides superior creep resistance, tensile strength, and longevity.
SA387 GR.91 CL.1 is utilized mostly in the power generation, petrochemical, and thermal processing sectors for the production of critical parts such as boilers, pressure vessels, and heat exchangers. The Grade 91 composition (9% Cr, 1% Mo, with Vanadium and Niobium) provides superior oxidation and corrosion resistance even under high temperatures.
We supply these plates with Mill Test Certificates, third-party inspection options, and international quality compliance. Available in various sizes and custom thicknesses, our plates are processed for easy weldability and long-term service reliability.
We at Conquest Steel & Alloys comprehend the need for uniform mechanical properties in high-stress applications. That's why our ASME SA387 Grade 91 Class 1 Plates are purchased and stocked to satisfy the precise needs of industries that specialize in safety, performance, and durability.
